In October I repotted the tree into a pumice-perlite soil mix due to a failure to thrive. It’s four months later, so let’s check in.
So it’s good and bad. The good is a fairly healthy crop of lovely green leaves. The bad is that there’s little to no branch growth – everything is staying very close to the living trunk. Looking back over the older pictures, I don’t think this has ever grown much away from it’s initial shape without me cutting it back. Referencing the original docs, this is supposed to be a shrub good for hedging, but I guess it doesn’t like the shallow pot. (Also, I don’t recall seeing any red flush in the new leaves.)
¯\_(ツ)_/¯ Maybe this will get more growth next spring?
